This TCP/IP stack is designed from the ground up to be lean, yet extremely fast and powerful. The aim of the driver is for it to be the perfect choice for applications ranging from small 8 bit low speed embedded devices needing TCP/IP functionality, to fast 16 and 32 bit devices that need to provide high throughput and performance without requiring huge resources. Whilst these aims may seem to contradict each other, accomplishing this is actually relatively straightforward with the right decisions made about the architecture of the stack. With a typical TCP/IP stack being comprised of a large number of lines of code it can be very daunting for anyone other than the original programmers to navigate and understanding it, let alone tailor it to their own needs with any sense of confidence. However the other main aim of this stack is for it to be easy for programmers to understand and customise if need be and it has been implemented with huge importance placed on the source code remaining simple, straightforward and easy to understand.

The driver code has been designed using ANSI compliant C compliers. Using the driver with other ANSI compliant C compliers and with other processors / microcontrollers should not present significant problems, but you should ensure that you have sufficient programming expertise to carry out any modifications that may be required to the source code. Embedded-code.com source code is written to be very easy to understand by programmers of all levels. The code is very highly commented with no lazy programming techniques. All function, variable and constant names are fully descriptive to help you modify and expand the code with ease.

The driver and associated files are provided under a licence agreement. Please see www.embedded-code.com/licence.php for full details.

The remainder of this manual provides simple guides to using the driver as well as a wealth of technical information about how the driver works. We welcome any feedback on this manual and the driver.
